GOVERNOR.

Specification of Letters Patent.

` yApplication filled November 1, 1910. Serial No. 590,986.

To all lwhom t may concern.'

Be it known that I, WILLIAM THOMAS STRAIN, citizen of the United.States, residing at Hanlin Station, in the county of Washington andState of Pennsylvania,

have invented certain new and useful Imlprovementsin Governors, of whichthe fol-t lowing is a specication.

This invention relates to improvements in governor valves for steam orother fluid engines and especially to a hydraulic governor and the mainobject of the invention is to provide a governor-which will maintain inan engine an absolutely uniform speed regardless of the variation of themotive power or the resistance.

Another object is to provide a device of this kind extremely simple inconstruction, yet eiiicient, durable and quick acting.

With these and other objects in view, I have constructed the governorvalve illustrated in the accompanying drawings, in which,

Figure 1. is a side .elevation of my improved governor taken partly insection, Fig. 2 is a vertical sectional view of; another form thereof,Fig. 3 is a valve chamber showing the valve and seat in .dotted lines,Fig. 4 is a cross sectional view taken on the line A-A of Fig. 1, andFig. 5is a plan view of the pump cylinder head.

Referring to the accompanying drawings illustrating the device andparticularly to Fig. 2 1 indicates the casing of a cylinder, saidcylinder being centrally divided Aby `a plate 2 into two chambers 3 and4. On one side of the cylinder casing an extension 5 is formed in whicha pump 6 is located, also the port 7 Jwhich 'leads from the chamber 3`to the pump and the port A8, which extends from the pump to the chamber4. Another extension 9 is formed in the casing 1, which receives thescrew threaded needle valve 10., Awhich is operated by a wheel 11. Inthis 'extension is also located a port 12, which leads from the chamber4 to the chamber 3. A valvey seat 13 is located in the port 12, uponwhich the needle valve 10 is vadapted to seat and close the port. A port14 passes from the upper part of chamber 4to the upper part of chamberk3 through an extension 15 in the casing 1. Within the chamber 4 islocated a weighted piston 16 which snugly fits into said chamber 4.Through the center of this piston passes a tube 17 on which saidpistonis slidable. This tube 17 extends from the upper part of the chamber 4,slightly above the opening to the port 14 and down thro gh the divisionplate 2 to the bottom wall 8 of the chamber 3 and is xedly securedthereto. Through this tube a stem 19 passes, to the upper end of thisstem is secured a weight 20. The pis-y ton 16 is secured to the stem 19by means of a collar 21 which straddles the upper end of the tube 17. Ahead 22 covers the upper end of the chamber 4, this lhead is providedwith an extension 23, .which is provided with an internal recess 24 toreceive the collar 'member 21 when the piston 16 occupies.

stem 25y which operates the valve 26. In the Patentediuay 21, 1912.

casing 5, which isintegral with the casing 1,

is a recess in which is located a pump 6 which is operated by .means ofthe shaft 27. s

To the outer end of this shaft is secured a pulley wheel 28. A sideplate 29 covers the pump casing 5. While I have shown a pump comprisinga form of cog wheels 30 and 30', I wish it understood that any preferredform of pump may be used in lieu thereof.

In Fig. 1 I show a slightly different arrangement. The tube 17 isdispensed with and the stem 31 is secured directly to the top of thepiston, while the stem 19 at this point of attachment with the valvestem 25 is secured to a link 32. The stem 31 also has a link 33 thereon.These links are connected by stems 34 and 35: Other stem 25 with thestem on the piston, the two .constructions are similar.

` In operation the revolution of the pulley operates the pump whichforces the liquid from the lower chamber through the port 8 int-o theupper chamber causing the piston to raise, should a greateramount ofliquid be forced into the upper chamber than can return to the lowerchamber through the port 12.

Having described my invention, I claim and desire to secure by LettersPatent 1. A governor comprising a casing divided into two verticallyconnected compartments, a fluid adapted to be circulated between saidcompartments, means for regulating the circulation of said fluid, apiston in one. ofsaid compartments, adapted to be oated by said fluid, atube passing passing through said tube, a weight on the upper endthereof, and a valve on the lower end'thereof.

2. A governor comprising a casing divided into two vertically connectedcompartments, .a fluid adapted to be circulated between saidcompartments, means for regulating the circulation of said fluid, apiston in one of said compartments, adapted to be floated by said fluid,a tube passing through said casing*v and valve, a valve stein passingthrough said tube, a weight on the upper end thereof, a Valve on thelower end thereof, said piston having anopening through the centerthereofl for the passage,

of said tube.

3. A governor comprising a casing divided into two vertically connectedcompartments, a fluid adapted to be circulated between saidcompartments, means for regulating the circulationof said fluid, apiston in one of said compartments, adapted to be floated by said fluid,a tube passing through said casing and valve, a valve stem passingthrough said tube, a weightl on the upper end thereof, a valve on thelower end there'- of, and means for fixedly securing said pis* i therebyand said valve operated.

.ton to said alv-e stem so that when said circulated between saidchambers, means within said last named conduit for regulating thecirculation of said fluid, a passage between the lower 4portions of saidchambers, a pump adapted for operation by a prime mover positionedwithin said passage, a tube passing through said casing Aand valve, avalve stem passing through said tube, and a valve upon the lower end ofsaid stem and adapted for operation upon a changein speed of the saidprime mover.

In testimony whereof I afliX my signature in presence of two witnesses.

WILLIAM VTHOMAS STRAIN. Witnesses:
